3. Battery replacement

In REG-D™ three variants of buffer batteries are used. Depending on the version and year of manufacture of the device, the batteries are used for different purposes (see case in this chapter). If the device is supplied with auxiliary voltage, the battery is not actively used. The battery serves as a back-up, in the event of auxiliary voltage failure. In general, the battery voltage is monitored and an alarm (status relay or status/operation LED) or message (output function for weak batteries with firmware version 2.24/3.24 or later (devices with characteristic S2)) is issued if the battery has low remaining capacity. This means that regular replacement of the battery is not necessary. Battery replacement may also be event-based. The delivery time-frames below are approximate. Due to repairs, for example, old devices can require a new CPU circuit board. Please check the battery type in the device. Regardless of the type of battery incorporated, in the event of a battery failure, the parameters should be saved as soon as possible, and always before the device is separated from the supply voltage. In devices fitted with MRAM, this is not necessary, but it is

• possible. Further notes on saving and restoring parameters are to be found in chapter 4

RAM-Backup, from page 16 onwards, or in the document "Backup and restore parameters

• f REG-D™(A) via Bootloader V02.pdf".

DANGER!

Danger of electric shock! Injury or death

 When replacing the battery, disconnect the device from all power

supplies (auxiliary voltage, control voltages). To replace the battery, first remove the plastic protective cover on the CPU board. Loosen the four screws and remove the cover. Once the battery has been changed, put the cover back on.

We take care of it. 10 Battery Replacement REG-D™ REG-D™ devices with MRAM (devices with the feature S2 from 09/2013, all others from 05/2014) These devices have a button cell battery to buffer the real-time clock. This means that no data are lost when the battery is removed. The time may have to be adjusted when the new battery is installed. Required battery: Lithium button cell 3 V Type CR1632 (order no. 570.0005) Service life: when the REG-D™ is in storage (no auxiliary voltage) > 6 years in duty cycle operation > 50% > 6 years The battery is installed on the outside of the CPU board in a suitable mount. To replace the battery, remove the existing battery from the mount and insert a new one. If you use tools to remove the battery, be careful not to damage the printed circuit board. NOTICE! Do not use pointed or sharp tools to remove the button cell! Avoid damage to the CPU circuit board

 Remove the button cell with your fingers and not with a tool.  If you have to use a tool, do not use a screwdriver or similar

pointed or sharp object. Remove the button cell Insert the button cell

11 Battery Replacement REG-D™ REG-D™ devices with SDRAM and plug-in batteries (feature S0 /S1 from 05/2009) In these devices, the battery acts as a buffer for the SDRAM and the real-time clock. Parameters are lost when the battery is removed. The devices therefore have a dual connection for the buffer battery. This means that the new battery can be connected before the used one is removed. For safety reasons, it is recommended to make a backup of the parameters for these devices. Required battery: Lithium 3V or 3.6V Type CR14250 1/2AA with cable and connector (order no. 570.0003.00) Service life: when the REG-D™ is in storage (no auxiliary voltage) > 6 years in duty cycle operation > 50% > 10 years Parameters are lost on removal of the battery!

 Connect the new battery before removing the used one.  Before replacing the battery, make a backup of the parameters (see chapter 4

RAM-Backup, from page 16 onwards). There are two battery connection points on the reverse side of the circuit board. To prevent any loss of parameters in the interim, you can place the replacement battery in the empty connection position. Take out the battery that needs to be replaced and remove carefully from the metal cover. Then you can push the new battery into the metal cover.

Parameters are lost when the battery is removed. Therefore, before replacing the battery in these devices, a backup of the parameters must be made. Parameters are lost on removal of the battery!

 Before replacing the battery, make a backup of the parameters (see chapter 4

RAM-Backup, from page 16 onwards). Required battery: Lithium 3V or 3.6V Type CR14250 1/2AA with soldering lugs (order no. 570.0001) Service life: when the REG-D™ is in storage (no auxiliary voltage) > 6 years in duty cycle operation > 50% > 10 years NOTICE! Mechanical/thermal damage to the CPU circuit board! Destruction of the conductor paths and/or the soldering pads

 It is recommended to have the battery changed in the factory.  If the battery has to be replaced on-site, this must only be done

by trained and qualified personnel, and in compliance with EMC Directives.

13 Battery Replacement REG-D™ The following describes in detail how to replace a soldered battery with three soldering lugs with a battery with two soldering lugs. When using a soldering iron, it is imperative to comply with general safety rules. Ensure the work is carried out with the utmost care and by trained personnel only. Turn the device so that the three soldering joints are in front of you. Unsolder the three soldering pins on the battery using a soldering iron. We recommend using unsoldering tape to remove the solder from the pins. Often, a little bit of tin solder on the top side of the suction tape helps to suck up the tin solder from the soldering joint. It is not advised to use a unsoldering suction pump as it can damage the soldering pads on the circuit board. Soldering battery with three soldering lugs CPU circuit board with soldering battery – plan view The soldering battery's soldering joints with three soldering lugs Unsoldering with unsoldering tape

We take care of it. 14 Battery Replacement REG-D™ To unsolder a soldered battery with two soldering lugs, the middle soldering point, which is between the two soldering lugs which have already been unsoldered, must be freed from

• solder. Before inserting the battery with two soldering lugs, the middle of the three

soldering pads on both the right and left side must be free of tin solder. Put the battery with two soldering lugs on the top side, in the central soldering pads, and ensure that the polarity of the battery is correct. On the underside of the CPU circuit board, the soldering pins must stand out from the middle of both soldering pads. Unsoldering the missing soldering pads for soldering batteries with two soldering lugs Soldering joints prepared for soldering battery with two soldering lugs Soldered battery with two soldering lugs – Check the polarity of the battery! Inserted soldered battery with two soldering lugs

15 Battery Replacement REG-D™ Solder the pins of the batteries again with the circuit board and check that the battery is properly supported. Finally, secure the plastic cover back in place on the CPU circuit board. Soldering the soldering battery with two soldering lugs

We take care of it. 16 Battery Replacement REG-D™

4. RAM-Backup

General The parameters of the Relay for Voltage Control & Transformer Monitoring REG-D™ are kept in the memory (RAM) by an internal battery, and are thus available unchanged after any interruption of the supply voltage. If the battery life is exhausted, the RAM loses data after any interruption of the supply voltage and the regulator will start with default parameters. To save the parameters independently of the regulator battery, since bootloader firmware version V2.12 it is possible to perform a RAM-Backup of the regulator. Hereby, parameters from the volatile memory (RAM) are secured in the non-volatile memory (flash) of the regulator. If, in addition, a REG-D™ firmware newer than V2.22 is used, the RAM-Backup is automatically restored in the RAM in case of loss of the parameters, and hence the parameters are restored too. In addition to automatic restoration, there is always the

• ption of manually restoring a RAM-Backup regardless of the firmware of the REG-D™.

Data backup It is recommended to carry out a RAM-Backup at the end of commissioning so that the parameters are saved on the spot in case of failure of the internal battery. REG-D™ devices with MRAM (as of 05/2014 or with the feature S2 as of 09/2013) In REG-D™ Relays for Voltage Control & Transformer Monitoring manufactured since 05/2014 (with feature S2 from 09/2013) a non-volatile RAM (MRAM) is used. In these devices no RAM-Backup is necessary, and for devices with the feature S2 this is not available in the bootloader. Performing a RAM-Backup The RAM-Backup can easily be performed on the regulator. For a manual RAM-Backup, the bootloader first needs to be started by pressing the key in the status menu for 5 seconds.

WARNING!

Control function While the regulator is in bootloader mode, all functions including the control functions of the REG-D™ are inoperative.
